I know a friend of a friend who bought a 383 chevy thru Summit and it spun the crank bearing after only being a year old. They took it apart and most of the parts were at the end of their life expectancy and couldn't be re-machined. He kept the block and heads and replaced the rest of it and Blueprint sent him a check that no where near covered the rebuild coct, and that was after weeks of battling them. Summit eventually told the guy to talk to Blueprint directly rather than keep pestering them.

For what he spent after the dust settled he could have had one redone locally with a dyno'd break-in included. Hindsight is 20/20.
